To all whom 1f mag/concern:

Be it known-that I, WENZEL C.'URBA1}IEK, a citizen of the United States,and residentl of Manitowoc, in the county of Manitowoc and State ofWisconsin, haveinvented .certain new and useful Improvements in- PorousHeads for Containers; and Ido hereby de- Clare that the following'is afull, clear,- and exact description thereof. fl' v My invention has forits'object toprovide a simple, economical and effective valvecontrolledporous head for fluid-containers,

the same being-adapted to receive fluiddressings or analogous liquids'chemicallyA prepared whereby@ said lliquids can -be applied directly toarticles being treated, the device beingespecially adapted for use kinconnection with cleaningfluids, which fluidsare distributed to the headincidental to inversion of the container whereby the said `head issaturated;

Incarryingout my invention I provide a conical gravity-controlleddouble-seating valve-member, which valve member is loosely` nestedwithina conical discharge nipple that l projects into an auxiliaryliquid containing i reservoir constitutingpart of the head, said conicalnipple' being alined'vwithl a lower feed aperture in the reservoir wall,which aperture is normallyfclosed by the valvemember whereby 'a quantityof Huid is trapped within said reservoir even though the valve isimperfectly seated, while at the .same time the main body of the fluidwithin the container or vessel is j practically sealed againstevaporation'r Another object of my invention is to forml the chamberportionof the head in two parts whereby cheapness of construct-ion willresult due to ready assemblage of said parts in con'unction with acontainer shankl which maye threaded or otherwise.-

With the above objects in view the invention consists in certaineculiar'ities of construct-ion and combinatlon of parts as set forthhereinafter with reference to the accompanying drawings and subsequentlyclaimed.

The'accompanying drawing represents an elevation of a container partlybroken away and in section provided with a porous head embodying thefeatures of my invention, the

n head being illustrated in section.

Referring by characters to the drawin 1 represents a vvessel orcontainer provi ed with a screw-threaded neck 2 to which .neck

.- is fitted the ,threaded lia-nge 3 of a porous head embodying myinvention, The head is Y formed with a lower concavofconvexed wall 4that is provided with a centrally disposed aperture formed by anupturned lipv 4 the terminal edge of which is slightly above the lowestplane of the wall. The upper edge of this wall is connected by aseam-joint 5 to an upper wall 6, which wall i's provided soL with-acentrally disposed conical discharge nipple 7, the same being flaredoutwardly vat itsv lower end in -alineme'nt with the lower wall apertureand at a slight distance there# from.l Loosel'y fitted within theconical discharge nipple is a conical valve-plug 8, the

lower face4 of which is adaptedy to seat againstthe upper edge of thelip kk4 about the lower wall aperture, while the conical face of saidvalve-plug is arranged to seat against the inner wallof the nipple inci:

dental to the vessel being inverted. Bythis construction' it #will beobserved that the upper and-lower walls '6 and 4 respectively, form anauxiliary'reservoir/withinV the head,

the `feed and discharge apertures being c'ontrolled bythe valve-plug.

The edges of a porous jacket flare,crimpedv within the seam-j oint 5 asshown and interposed betweenthe jacket' and upper wall `6. of thereservoir there is a -filling orpadof absorbent material 9', whichmaterial is normally saturated-"with the liquid that 1s aol fedthroughthe discharge ni ple. Afterthc, y

edges of the jacket'9 have een secured to the seam, the upperinturnedxedge of the flange 3 isadjusted 'to the seam, whereby thejacket lis further secured and the partsh draw-n tightly together due tothe fact that.'

as said shank is screwed into position it will cause the lower edge ofthe seaml 5i to seat securely upon the mouth of they container.

As s own I also provide-a slip cover 10 which is tted over the jacket 9and upper portionof the .shank 3 whereby the moist pad Iis protectedincidental `to the container ture and hence it will be observed that thecontents of the bottle will be prevented from evaporation. Should thevessel be inadvertently dropped upon its side there will be noappreciable leakage owing to the factthat the pressure of the liquidwill cause the valve-plug to seat within the nipple and the smallquantity of liquid which will escape through the feed-nozzle will betrapped within the reservoir. It is also apparent that should themoisture in the pad be eX- hausted that theoperator can, by slightlygyrating the container cause more of the liquid to be fed thereto.

I claim: i

A porous head for liquid containers comprising a concavo-convexed lowerwall section having an upturned lipped feed aperture centrally thereof,an upper wall section in seamed engagement with the lower wall section,the upper wall section being provided with a centrally disposed depend'ing conical discharge nipple, said wall sections constituting areservoir, a conical valve-plugloosely nested within the nipple adaptedto serve alternately as a closure for said nipple and feed aperture, apad of absorbent material fltted over the Aouter face of the upper wallsection, a porous jacket fitted over the pad having its edges securedwithin the seam of the two wall sections, and a detachable threadediange fitted over the wall section seam engageable with the porousjacket, whereby said jacket and the pad are secured to the reservoir,the threads of the flange being provided for attachment to the head of acontainer.

In testimony that I claim the foregoing I have hereunto set my hand atManitowoc in the county of Manitowoc and State of Wisconsin in thepresence of two witnesses.
